BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a cooler, particularly to one employing atwo-step cooling technique of air cooling and water cooling for quicklycooling off high-temperature liquid or gas in a heat exchanger, havingexcellent effect of quick cooling.

2. Description of the Prior Art

A conventional cooler for lowering the temperature of high-temperatureliquid or gas is provided inside with a cooling pipe with a water inletat one end and a water outlet at the other end. The conventional cooleris further bored with an inlet and an outlet of high-temperature liquid.To cool off high-temperature liquid, it is conveyed into the coolerthrough the inlet to be cooled off by cooling water in the cooling pipe.After lowering temperature, the liquid will flow back to a main body ofthe cooler for use through the outlet, and then heated-up cooling waterproduced by heat exchange will be guided out of the water outlet.However, the conventional cooler carries out cooling only by watercooling, so it needs a comparatively large water tank and takes acomparatively long period to carry out cooling for lowering thetemperature of the high-temperature liquid so as to enable the liquid tobe used again. In addition, the heated-up cooling water is drained outthrough the water outlet and unable to be recycled for use, thus wastingresources.

The at least one air-cooling radiating device 11 disposed in the mainbody 1 is provided with a plurality of cooling fins 110.

The least one fan 12 is installed at an outer side of the main body 1.

The least one wind intake 13 disposed at a side of the main body 1 iseach provided with at least one air filtration net 130.

The least one cooling pipe 14 is provided with an upper inlet 140 and alower outlet 141 respectively disposed at both ends thereof, an upperbent portion passing through the plurality of cooling fins 110 of the atleast one air-cooling radiating device 11, and a lower bent portionpositioned near the lower outlet 141 and above the water tank 10.

The at least one water-blocking device 15 abutting one side of the atleast one air-cooling radiating device 11 is provided with a pluralityof sloping plates 150 formed therebetween with air-current passageways151.

The at least one water-cooling radiating device 16 is disposed atanother side of the at least one water-blocking device 15 and below thespray pipe 102. The at least one water-cooling radiating device 16 isprovided with cooling material 160 and at least one drip-holding tray161 positioned below the cooling material 160 and arranged with aplurality of water holes 162 for receiving water overflowing downwardfrom the at least one water-cooling radiating device 16 and the at leastone water-blocking device 15 and for providing further cooling function.The lower bent portion of the cooling pipe 14 is positioned below thedrip-holding tray 161.

A first preferred embodiment of the cooler in the present invention, asshown in FIG. 1, is used to cool high-temperature gas, in which oneair-cooling radiating device 11, one water-blocking device 15 and onewater-cooling radiating device 16 are disposed in the main body 1; onefan 12 is installed at one side of the main body 1; one wind intake 13is installed at another side of the main body 1; and one cooling pipe 14disposed in the main body 1 has an upper bent portion passing through aplurality of cooling fins 110 of the air-cooling radiating device 11 anda lower bent portion wound below a drip-holding tray 161 of thewater-cooling radiating device 16. The cooling pipe 14 further has anupper inlet 140 positioned near an upper end of the air-coolingradiating device 11 and a lower outlet 141 positioned below the lowerbent portion of the cooling pipe 14. In using the first preferredembodiment, referring to FIG. 2, when the cooler is operated, the waterpump 100 of the water tank 10 will pump cooling water to the spray pipe102 through the water pipe 101, and synchronously the spray pipe 102will spray the cooling water toward the water-cooling radiating device16 and the cooling material 160, and the overflowing cooling water willflow downward to pass through the drip-holding tray 161 and get into thewater tank 10. Meanwhile, the fan 12 is timely started to rotate andproduce suction force to suck air into the main body 1 through the windintake 13. After cooled by the cooling material 160, the air will becomecool moisture and enter the air-cooling radiating device 11 through theair-current passageways 151 of the water-blocking device 15. When thehigh-temperature gas is conveyed into the cooling pipe 14 through theupper inlet 140, it will receive a first-step cooling by the coolmoisture. After the high-temperature gas in the cooling pipe 14 iscooled, its density will become great and drop to the lower bent portionof the cooling pipe 14 to receive a second-step cooling by the coolingwater dropping from the water-cooling radiating device 16.

A second preferred embodiment of the cooler in the present invention, asshown in FIG. 3, is used to cool high-temperature liquid, in which thestructure is similar to that of the first preferred embodiment exceptthat the upper inlet 140 of the cooling pipe 14 is positioned near alower end of the air-cooling radiating device 11, and the lower outlet141 of the cooling pipe 14 is positioned above the lower bent portion ofthe cooling pipe 14 and just under the drip-holding tray 161. In usingthe second preferred embodiment, when the high-temperature liquid isconveyed into the cooling pipe 14 through the upper inlet 140 of thecooling pipe 14, air is sucked into the main body 1 by the fan 12 andthen passes through the cooling material 160 to become cool moisture.Then, the cool moisture enters the air-cooling radiating device 11through the air-current passageways 151 of the water-blocking device 15to make the high-temperature liquid received a first-step cooling by thecool moisture. And then, the high-temperature liquid will be conveyed tothe lower bent portion of the cooling pipe 14 through the cooling pipe14 to receive a second-step cooling by the cooling water dropping fromthe water-cooling radiating device 16.

A third preferred embodiment of the cooler in the present invention, asshown in FIG. 4, is used to cool high-temperature gas, in which twoair-cooling radiating devices 11, two water-blocking devices 15 and twowater-cooling radiating devices 16 are oppositely disposed in the mainbody 1; one fan 12 is installed on a top of the main body 1; two windintakes 13 are respectively disposed at two sides of the main body 1;and one cooling pipe 14 disposed in the main body 1 has an upper bentportion passing through a plurality of cooling fins 110 of the twoair-cooling radiating devices 11 and extending downward through adrip-holding tray 161 and has a lower bent portion wound below thedrip-holding tray 161. The cooling pipe 14 further has an upper inlet140 positioned near and between upper ends of the two air-coolingradiating devices 11 and has a lower outlet 141 positioned downwardly ata lower part of the lower bent portion of the cooling pipe 14, thusproviding a cooler capable of cooling larger volume with more fastness.In using the third preferred embodiment, the high-temperature gas isconveyed into the cooling pipe 14 through the upper inlet 140 of thecooling pipe 14 for receiving a first-step cooling by cool moisture.After the high-temperature gas in the cooling pipe 14 is cooled, itsdensity will become great and drop to the lower bent portion of thecooling pipe 14 to receive a second-step cooling by the cooling waterdropping from the water-cooling radiating device 16. Thus, thehigh-temperature gas can be quickly converted into normal-temperatureair to be recycled for use.

A fourth preferred embodiment of the cooler in the present invention, asshown in FIG. 5, is used to cool high-temperature liquid, in which thestructure is similar to that of the third preferred embodiment exceptthat the cooling pipe 14 having an upper inlet 140 positioned near andbetween lower ends of the two air-cooling radiating devices 11 and has alower outlet 141 positioned upwardly at an upper part of the lower bentportion of the cooling pipe 14 and just under the drip-holding tray 161.In using the fourth preferred embodiment, the high-temperature liquid isconveyed into the cooling pipe 14 through the upper inlet 140 of thecooling pipe 14 for receiving a first-step cooling by cool moisture. Andthen, the high-temperature liquid will be conveyed to the lower bentportion of the cooling pipe 14 through the cooling pipe 14 to receive asecond-step cooling by the cooling water dropping from the water-coolingradiating device 16. Thus, the high-temperature liquid can be quicklyconverted into normal-temperature liquid to be employed again.

As can be understood from the above description, this invention has thefollowing advantages.

1. In the cooling system of this invention, the fan 12 is started toactuate air current as in an air-cooling heat exchanger for a first-stepdirectly cooling by cold air; and the water pump 10 functions to actuatewater to circulate as in a water heat exchanger for a second-stepdirectly cooling by cooling water. By so designing, after carrying outthe two-step cooling for heat exchange to lower temperature, the hightemperature liquid or air coming into the cooling pipe can quickly becooled off, having excellent effect of quick cooling.

2. Provided with heat exchangers for carrying out two-step cooling, thecooler of this invention has much better cooling effect than theconventional cooler that is provided with only one heat exchanger forcarrying out one-step cooling.
